    Default psu pcb board damage from miss screw wrong hole

    hello everyone

    so i got new psu, and then i align the psu with psu cage in my pc case
    and i just realized i put screw on wrong hole as the other hole not aligned

    and after i unscrew i found out its not screw hole, rather its heatsink hole (similar size), it didnt make much damage other than little scratch
    but the screw seems grind abit of edge PSU PCB main board...
    will it damage the PSU ?

    it should be okay based what i know, but again i am kinda paranoid
    as i only know little about electronics basic/knowledge
    so decide to ask here for expert help

    hope someone can confirm

    thanks in advance

    hello

    its corsair HX750i... its the hexagonal hole near power plug, the edge bottom one (main PCB side)
    one or two of its hexagonal hole align with my casing psu cage
    so i didnt realize its not the correct hole, plus the resistant when screwing it not hard (almost same like tight new hole)

    i am using image from hx750i review on your site

    so from the hole, the screw grind edge those area i circling red


    it wont make any problem right ?

    I doubt it. There's no components or traces there.

    boss, i think u get it mistake what i mean
    its not real picture of my PSU main board, i just use picture from your review, just to show the area hit by the screw

    this image not might not clear enough.. but hopefully this make more clear


    the upper right side corner of power plug

    there is screw hole in my pc casing, but not on the psu
    what is bummer is that i miss screw on main pcb area... its not deep, but it hit/grind the pcb... it not really clear, but it seems the screw make hole to the clear film/plastic, and also grind up some pcb

    well its on the edge, and its not deeper than few milimeters

    Should work just fine IMO. If you feel worried, try just turn it on and carefully measure the output voltages with a multimeter.

    Looks like he understood you perfectly.

    You can't damage there much, because like Jon said, there aren't any traces or components at that place.

    But why did you put the screw there? PSU upsidedown?

    Yeah. I understood you. This isn't an uncommon problem. I've even seen some PCBs cracked by too long screws, but typically the PSU works fine.
